Wearable Multi-Sensor Unit for Remote Monitoring Physiological Parameters

Areas of Application:

• Wearable Monitoring and Measurements
• Telemetry
• Remote Monitoring

Engineering Expertise involved:

This project focuses on a cost-effective portable system for constant real-time measurement, processing and wireless transmission of telemetry data with required accuracy while withstanding acceptable degree of environmental artifacts. The platform is intended for remote monitoring scenarios, but the design approach is broadly applicable to connected telemetry products.

The unit performs data sampling, analog signal pre-conditioning and normalization, and wireless transfer via Bluetooth Low Energy (BLE) radio link to the base station and networked PC for further post processing and analysis. For immediate detection of abnormal data patterns, initial data analysis will be performed in the host application at the base station, while more detailed evaluation can be executed on a server data management platform for further processing and review.

Analog Front-End (AFE) electronics is designed to sample and process ultra-low electrical potentials. The signal pre-conditioning techniques involve signal denoising (i.e. active/passive versions of high-pass filters (HPF) and low-pass filters (LPF), baseline wandering stabilization, signal differentiating, automatic gain control, etc.).

The signal-processing approach includes denoising, filtering, gain control, synchronization, peak detection, segmentation, SNR estimation, and pattern-analysis support to improve data quality and help identify abnormal conditions earlier.
